attacks.

Input passed via the query string in index.php isn't properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

Successful exploitation requires that the user is using the Microsoft
Internet Explorer browser.

The vulnerability has been confirmed in version M1.1 RC1. Other
